63R-43

Thanks for the ^46 result, Neil. Here is data for 63R-43:

[X D12] ~10 (ext in prog)
[X D2] /46
[X D6] <62
[X=D] ^46

d[D X6] /5

Key: X = hit-and-split (13/10* 24/20), D = Down (13/10* 13/9). Margins are in thousandths. Before brackets, d = dmp; else assume money. After brackets is a bot symbol (~ Snowie, / GnuBG, < XG 3-ply, ^ XG 4-ply) and the number of trials in thousands. For example, "d[D X6] /5" means that at dmp, D is best and X is -.006 in a GnuBG rollout of 5000+ trials.

Here are aggs (bot aggregates) for six related positions:

64R-42 [X D16]
64R-32 [X D12]
63R-43 [X D4]
63R-32 [X D12]
62R-43 [X D8]
62R-42 [X D5]

At gammon save, X is better by far. At gammon go, D is better by far. At dmp, according to GnuBG rollouts of 5k trials, D is better for 63R-43 and 63R-32, but X is better for the other four positions.
